Yes, that's what I meant to say about Doc Rivers. & no, I don't think Brown was a truly terrible coach -- or, to put it another way, just as there are few coaches who can make a team significantly better, there are also few coaches who make their teams significantly worse.
The truth is that the Sixers roster is not as good as some people think. 2 key mistakes are to imagine that Tobias Harris is a plus player at all, & that Al Horford is a plus player at this stage of his career.
But the biggest mistake is over-valuing Joel Embiid. That's easy to do, since he is such a magnificent player in so many ways.
Embiid gets over-valued to a degree, because no one notices how much he turns the ball over. No one factors in those extra TOs when assessing his offensive impact. But, in fact, those TOs are a part of his offensive impact & do need to be accounted for.
Embiid is a high-volume scorer. & his TS% is well above average (especially given his usage) -- but not great. But, if you factor in the number of his turnovers above the average, then the overall result of his offense is still high volume, but it's no longer efficient.
If you take an average big & calculate his eFG% as if his turnovers were simply missed shots rebounded by the other team, the result is 46% efficiency. Do the same for Embiid, & the result is 42.6% efficiency. Per 40 minutes last year, Embiid accounted for just over 25 shots plus turnovers. Really, the best thing about him offensively was that he got to the line a whole lot & shot FTs well.
Overall, Philly's offense this year was below average -- largely b/c their volume shooters weren't high % shooters. I can't see how Brown can be held responsible.
Remember -- if you don't like the post above: blame Doc not me.
